思路：重写ListView的setOnTouchListener事件；
ListView.setOnTouchListener(new OnTouchListener(){
@Override
public boolean onTouch(View arg0, MotionEvent arg1) {
// TODO Auto-generated method stub
hideMenu();//隐藏菜单
return false;
}
});
延申：
点击窗体空白地方隐藏菜单或软键盘思路一样:
@Override
public boolean onTouchEvent(MotionEvent event) {
// TODO Auto-generated method stub
hideMenu();
return super.onTouchEvent(event); }
